From 49bc3f1e3ff8416908fc986bb60b444a75a1722d Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Sun, 28 Feb 2021 12:17:28 +0100 Subject: vif: T3349: use fixed ordering when enabling parent and child interface When a VIF/VLAN interface is placed in admin down state but the lower interface, serving the vlan, is moved from admin down -> admin up, all its vlan interfaces will be placed in admin up state, too. This is bad as a VLAN interface will become admin up even if its specified as admin down after a reboot. To reproduce: set interfaces ethernet eth1 vif 20 disable set interfaces ethernet eth1 disable commit delete interfaces ethernet eth1 disable commit Now check the interface state and it returns UP,LOWER_UP 7: eth1.20@eth1: mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:50:56:b3:09:07 brd ff:ff:ff:ff:ff:ff inet6 fe80::250:56ff:feb3:907/64 scope link valid_lft forever preferred_lft forever --- python/vyos/ifconfig/wireless.py | 10 ---------- 1 file changed, 10 deletions(-) (limited to 'python/vyos/ifconfig/wireless.py') diff --git a/python/vyos/ifconfig/wireless.py b/python/vyos/ifconfig/wireless.py index 6c0eeec44..748b6e02d 100644 --- a/python/vyos/ifconfig/wireless.py +++ b/python/vyos/ifconfig/wireless.py @@ -63,13 +63,3 @@ class WiFiIf(Interface): # re-add ourselves to any bridge we might have fallen out of if bridge_member: self.add_to_bridge(bridge_member) - - # Enable/Disable of an interface must always be done at the end of the - # derived class to make use of the ref-counting set_admin_state() - # function.
